Flashcards in Day 9 -GU2 Quiz Deck (20):
1

HypoNa, low serum osmolality, high urine osmolality

SIADH

2

Next step mgt: peaked T waves

Calcium gluconate

3

Most common cause of death in dialysis pts

CV disease (prevent w/ daily ASA & statin)

4

Electrolyte abnormality: peaked T waves

Hyperkalemia

5

Electrolyte abnormality: flattened T waves

Hypokalemia

6

Electrolyte abnormality: U waves

Hypokalemia

7

Electrolyte abnormality: QT prolongation

Hypocalcemia

8

Electrolyte abnormality: QT shortening

Hypercalcemia

9

Distinguishing features of RTA Types

Type 1: high urine pH > 5.3, decreased serum K, variable serum bicarb (often low); Type 2: urine pH > 5.3, low serum K, bicarb low; Type 4: urine pH

10

Risk of correcting hypernatremia too rapidly - recommended rate

Cerebral edema; 12 meq/L/day

11

Risk of correcting hyponatremia too rapidly - recommended rate

CPM; Also 12 meq/L/day (definitely no more than 20 meq/L/day)

12

Options for correcting hyperkalemia (by shifting K+ into cells)

Sodium bicarb, Alb nebs, Insulin + glucose; Not by shifting: Loop diuretics, Kayexalate

13

DDx for euvolemic hyponatremia

SIADH, Hypothyroidism, Polydipsia

14

Meds known for causing hyperkalemia

ACEi/ARBs, beta blockers, digoxin, potassium-sparing diuretics

15

Meds known for causing hypokalemia

Diuretics (loops, thiazides, carbonic anhydrase inhibitors, etc.), Albuterol, Insulin

16

Tx Nephrogenic DI

HCTZ +/- Indomethacin; If Lithium induced, HCTZ + Amiloride

17

Sodium levels corrected for hyperglycemia

As glucose levels reach above 100, for 100 mg/dL of glucose add 1.6 mEq/L of Na; Above 400 of glucose, add 2.4 meEq

18

Total Ca levels corrected for hypoalbuminemia

As albumin drops below 4, for every 1 g/dL, Ca decrease 0.8 g/dL

19

DDx nongap metabolic acidosis

Diarrhea, RTA, TPN (i.e., hyperalimentation)

20

Meds necessary in pts w/ ESRD

Statins (reduce CVD risk & reduce sepsis risk for dialysis), Vit D, Iron, EPO (not want to get Hb above 11-12), Phosphate binders (calcium agents usually), Daily ASA (81 mg); Bp goal
